The Reformation started in Germany. Pretty Christian place.
Yes, Jews were blamed for killing Christ. They were also reviled for the anti-Christian practice of usury. They were depicted as devious controllers of money and wealth with vast secret powers. They tended to be "different" and not mix with ordinary culture. They were accused of vile religious rituals. And on and on.
Antisemitism was widespread in Europe and also fairly common in America. Pro-fascists such as Father Coughlin railed against Jewish influence in banking and government in the 1930s. Later on Jews were said to control Hollywood and many newspapers. Jews were closely linked to communism and socialism. Jews played prominent roles in America's Civil Rights Movement.
The reformation had nothing to do with the Jews, kid. Have you people ever read a history book or watched a GD documentary?
